Shift key doesn't work in my emacs

Question

I run emacs in gnome-terminal with -nw option, it works well except for some key shortcuts that include the shift key. For example, when I execute C-M-S-v (scroll-other-window-down), only C-M-v keys are recognised by Emacs which in turn scrolls the other window up.

I tried these key shortcuts in a GUI Emacs, everything works properly.

I guess there must be something wrong about the gnome-terminal or other terminal emulators, such as iTerm on Mac OS which I encountered the same problem.

How could I enable shortcuts that include shift key in a gnome-terminal?

Answer 1

The VT100 and terminals derived from it simply does not recognize the concept of a shifted control key.
